Android Signing

[Dan Friedman]

I am trying to update an Android app that was previously release on the Google Play Store.   When I went to upload the Bundle, I got this message:

“To upload an Android App Bundle you must be enrolled in Play App Signing.”

With a little research, I found the App Signing area under “App Integrity”.   I tried to follow the directions, but I just get errors.  Anyone done this?  If so, do you have any guidance on this?

Thank you in advance,
